Play Stack Em for Free in Demo Mode by Hacksaw Gaming

Stack Em review

Stack Em has a vintage cartoon theme with an aesthetic that brings to mind the first pieces animated by Disney.

Players will wander into a wholesome natural scene and meet a pair of springy characters. They bob up and down on either side of a reel of vintage symbols.

This slot is a good fit for players feeling nostalgic for retro cartoons or those who’ve enjoyed getting into Cuphead.

Graphics, Sounds and Animations

The whimsical percussion soundtrack upholds the retro mood of the game, and bubble sounds accompany the movement of the reels.

As one might expect in an old-fashioned cartoon, the backdrop behind the reels is much more lushly animated than the characters. Players will see a peaceful landscape of trees and fields that give a relaxed feeling.

Stack Em’s kooky mascot, Canny the Can, is dressed in a pair of white gloves and an elegant tophat, bringing to mind the iconic cartoons of the 1930s. His unmoving grin is almost unsettling, but right on theme for this game.

Canny’s companion, a tiny ink-black mouse named Mona, bounces on the other side of the reels looking adorable and a bit fearful.

The symbols are animated in an engaging vintage style with an eclectic collection of items including leaves, skulls, dead birds, snakes, and hands giving a thumbs up. These cryptic symbols give this game an eerie undertone, despite its cute first impression.

Overall, the soundtrack and animation capture the energy and vibe of vintage cartoons.

Gameplay

Stack Em is a five reel, six row slot.

Players are awarded wins for landing at least 5 connected matching symbols.

When players land a winning combination, the winning symbols remain on the reels and the non-winning symbols fall away, allowing players to build bigger winning combinations.

Wilds, Bonuses and Free Spins

The Wild symbol substitutes for all symbols except the Free Spins symbol.

When players land a win, a multiplier value appears below each reel with a winning symbol. This number reflects the number of winning symbols present in the reel. This collection of multipliers is combined to create a larger multiplier that is applied to players' winnings.

When players land 3 or more Free Spins symbols, the Free Spins feature begins, starting with five free spins.

Throughout the feature, wins increase a multiplier that is applied to players’ winnings.

The Free Spins feature also allows a special X symbol to appear. When the X symbol is pat of a winning combination, the multiplier is applied to the value of the win.

A Question Mark symbol is also added to the reels. When this Question Mark symbol lands it provides a random benefit from a list that includes things like additional free spins and multiplier increases.
